Dataset for "Relationships of the Hygroscopicity of HULIS with Their Degrees of Oxygenation and Sources in the Urban Atmosphere, J. Geophys. Res. Atmos."

The hygroscopicity of humic-like substances (HULIS) from Beijing aerosols and its relationship with the degrees of oxygenation and sources were investigated. The dataset in the Excel sheet contains the measured hygroscopicity parameter (κ), elemental ratios, and estimated intrinsic κ for HULIS, and the mass-based source contributions to HULIS, the κ estimated for total organic aerosol and the high-polarity fraction of water-soluble organic matter, and other data for Zhou et al. in Journal of Geophysical Research: Atmospheres. The concentrations and elemental ratios of HULIS and the source contributions to HULIS (both in µg/m3 and percentage) were taken from Zhou et al. (2021). The dataset is based on the work supported by JSPS KAKENHI JP19H04253 and the National Natural Science Foundation of China (grant no. 41625014).
